Simple for me really...I had had an VX6900 (Verizon branded HTC Touch) previously, and I had gotten used to not having a mechanical keyboard....so my choices boiled down to 2 phones really, the Inc and the X. I went with the X because of the increased screen size, better camera, HDMI output, and large storage capacity out of the box.
Not too mention the X is just plain sexy...sexier than 2 nekkid pigs actually...dancedroid

I have big hands too...size is perfect. I liked what I saw even though I didn't know anything about droid phones. Been since august ...couldn't be happier with the dx. Oh yeah, I don't like physical keyboards. Thumbs too big.

Had a Droid 1, wife had an Eris. Bought two Fascinates on release day with the BOGO promo, but had to add a line to get them because we only had one upgrade available.

After one week with the Fascinate, I wanted to go back to my Droid 1 and get my upgrade reinstated. However, my wife didn't want to go back to her Eris (I can't blame her), even though I had it rooted, overclocked and on a custom rom.

Returned the Fascinate, and waited one week for my X to come in. Received the OTA 2.2 update on the 2nd day of my X experience, and have been eXtremely happy with the X.

My X is rooted, running on Ultra Low Voltage, and on custom roms now, but not overclocked as I've seen no need to overclock her.

It was newest, and most powerful (as far as I knew) Android when I decided to buy. It also looked to be very popular. Why were these important to me? Because they all help to insure that it will have a long healthy support cycle.

The big screen was also a big plus. I don't type enough on my phone to care about a real keyboard.

I was due for an upgrade and had been considering a smartphone for some time. I seen some specs of the Droid X a little while before was it release, it was untouched by any other android device on the Verizon network. All the videos i seen of it before being released made me crave it even more. I had it on release date, got a junk phone, but received a new one a couple of days later and I Love It. As of right now i wouldn't trade it for any other smart phone. I am getting a replacement in monday because the main mic died.
